PS3 problems

[philabong2]

ok i experienced a few problems with my ps3 lately when it didnt want to read anything else but BoP. I restored default settings and erased evry game files exept BoP and it seems to be reading evry game ok...

But now I can't login to PSN... is it my PS3 acting up again or is the network down for maintenance or something? I tried reseting the modem and rooter and it didnt work.

I'm using a wired connexion set up where I use the same cable coming from the rooter for my PC and the PS3 - I unplugg one of the two when using the other cause the rooter is at the other end of the appartment - and I have absolutly no problem goin online with my PC. I have a PS3 slim barely 3 months old (store warranty expired), should i send it back to Sony?
